PIPE-JOINT.

To all whom it may concern:

Be it known that we, CHARLES H. KEN- NEDY and JAMES W. LAWRENCE,citizens of the United States, residing at Dahl en, in

the county of Hamilton and State of llinois, have invented certain newand useful Imrovements in Pipe-Joints, of which the folbetween thesections of pipe and which obviates all likelihood of separationthereof, which gives rise to disadvantages of obvious this inventionapipertains.

Simplicity an chea ness of construction are essentially desirab e inmeans such as above mentioned and are secured in thepractical embodimentof the invention.

1 For a full understandin of the'invention and the merits thereof analso to acquire a knowledge of the details of construction 0 the meansfor effecting the result reference is to be had to the followingdescription and accompanying drawings, in -which i Figure 1 is aperspective view showing sections of a pipe invention a p ed thereto. Fi2 is v a sectional view rin ingout more 0 early the arrangement of t espring-catches by which the sections of the pipe are connected. Fig. 3is a horizontal sectional view on the line XX of Fig. 2. Fig. 4 is adetail perspective view of one of the catches.

Corresponding and like parts are referred to in the followm in all theviews 0 the drawings by the same reference characters.

In the drawings the numerals 1 and 2 designatetwo pipe-sections whichare joined together by means of the invention. The section 1 is providedat. opposite sides thereof and near Its ends with openings 3 of asuitable form to receive noses 4, constituting the engaging portions ofcatches 5, applied to the section 2 of the pipe The catches 5' arespring-catches made from metal and are attached at one end, as shown at6, to thepipe-section 2 by means of'rivets or any suitable fastenings.The opposite ends of the catches 5 are provided with the, noses 4,which. engage the pipe-section 1 by entering the openings 3 ISpecification of Letters Patent.

above mentioned. It will be observed that when the spring-catches 5coact with the sec: tion 1 the two sections of the pipe will beconnected by a positive interlocking connection, which will obviate alllikelihood of separation thereof.

The noses of the catches 5 roject through openings- 7 in the section 2,wiiich openings 7 are adapted to register with the openings 3 in thesection 1. The noses 4 of the catches are preferably beveled, so that asthe pipesection 1 enters the pipe-section 2 in joining,

the ends with the usual telescopic action the section 1 will engage thenoses of the catches and spring the same outwardly preparatory toengaging with the openings 3. It Is desirable that thenoses 4 of thecatches be provided with side flan es 8 to effectively close theopenings 3 an 7 to prevent escape of smoke, sparks, or any prroducts ofcombustion. Furthermore, the ee extremities of the catches 5 are turnedoutwardly slightly toform fingerpieces 9 to admit of ready manipulationof the catches.

, It will of'course: be understood that all of the sections in thelength of the pipe will be connected by the interlocking sectionshereinbefore set forth, such being located at the 'ends thereof. It willof course be understood that the springs 5 are to be secured to theelbow.

Having thus described the invention, what is claimed as new is 1. In aipe-joint, the combination of meeting en s of pipe-sections, one sectiontelescoping in the other section at the adjacent end ortions, saidsections being pro- ,vided with registering openings, catches secured atone end to the end of the outermost sections, the opposite end portionsof said catches being rovided wit suitable noses to pass throng theregistering openings in the sections and secure the latterto ether, the.free ends of the catches being ormed with outwardly-bent extensions toprovide finger-pieces by which to manipulate said
